摘要：The invention relates to improvements to safety devices preventing the tipping of a pair of sheeting boards 1, 2. It is characterised in that provision is made, on top of each upright, for two articulated connecting rods 5, 6, 7, 8 at a certain distance from each other and articulated themselves to a central unit 17 so as to form two parallelograms which are deformable between two extreme limits, when the sheeting boards 1, 2 are handled by a lifting means. <IMAGE>
